SYNOPSIS

 use alienfile;
 plugin 'Probe::CommandLine' => (

 );

 

DESCRIPTION

This plugin probes for the existence of the given command line program.  

PROPERTIES

 

command

The name of the command.  

args

The arguments to pass to the command.  

secondary

If you are using another probe plugin (such as Alien::Build::Plugin::Probe::CBuilder or Alien::Build::Plugin::PkgConfig::Negotiate) to detect the existence of a library, but also need a program to exist, then you should set secondary to a true value. For example when you need both:

 use alienfile;
 # requires both liblzma library and xz program
 plugin 'PkgConfig' => 'liblzma';
 plugin 'Probe::CommandLine => (
   command   => 'xz',
   secondary => 1,
 );

When you don't:

 use alienfile;
 plugin 'Probe::CommandLine' => (
   command   => 'gzip',
   secondary => 0, # default
 );

 

match

Regular expression for which the program output should match.  

match_stderr

Regular expression for which the program standard error should match.  

version

Regular expression to parse out the version from the program output. The regular expression should store the version number in $1.  

version_stderr

Regular expression to parse out the version from the program standard error. The regular expression should store the version number in $1.
